8.3 Contour milling
Parameter Description
Retraction Planar retraction mode:
Quadrant:
•
Part of a spiral (only with path milling left and right of the contour)
Semi-circle:
•
Part of a spiral (only with path milling left and right of the contour)
Straight line:
•
Retraction
•
strategy
•
R2 Retraction radius - (only for "quadrant or semi-circle" retraction)
L2 Retraction distance - (only for "straight line" retraction)
Lift mode If more than one depth infeed is necessary, specify the retraction height to which the
tool retracts between the individual infeeds (at the transition from the end of the contour
to the start).
Lift mode before new infeed
Z0 + safety clearance

•
No retraction
•
FZ Depth infeed rate - (only for G code)
FR Retraction feedrate for intermediate positioning - (not with "No retraction" lift mode)
FS Chamfer width for chamfering - (only for chamfering machining)
ZFS Insertion depth of tool tip (abs or inc) - (for machining only)

Contour pocket/contour spigot (CYCLE63/64)

Contours for pockets or islands
Contours for pockets or islands must be closed, i.e. the starting point and end point of the
contour are identical. You can also mill pockets that contain one or more islands. The islands
can also be located partially outside the pocket or overlap each other. The first contour you
specify is interpreted as the pocket contour and all the others as islands.
Contours for spigots
Contours for spigots must be closed, i.e. the starting point and end point of the contour are
identical. You can define multiple spigots, which can also overlap. The first contour specified
is interpreted as a blank contour and all others as spigots.
